Android: WhatsApp is one of the biggest chat apps in the world, but it's still been missing one key feature until now: Video calling. If you're running the WhatsApp beta, you can try it out. According to a report by Android Police, WhatsApp has quietly begun testing video calling on a recent beta build. If you want to try it out, you can either download the latest beta from APK Mirror or sign up for the official WhatsApp beta program on Google Play. Once the beta is installed, you may need to clear your app data before the option will show up (just be sure to backup your chats first). Currently, you can only place video calls to other beta users. If you call someone without the beta, they will only receive a voice call.
